DESCRIPTION OF THE PRIOR ART IO-Methyl- -octalone-2 of the formula is known, for example, from J. Chem. Soc. 53-60 (1937) [see also J. Org. Chem. 29, 2501-2505 (1964)].

SUMMARY OF THE INVENTION It has now been surprisingly found in accordance with the present invention that IO-methyloctalone-2 possesses particular odorant properties which make it excellently suited as a component of odorant compositions.

The present invention is based on the foregoing finding and is concerned, in one of its aspects, with odorant compositions which contain IO-methyl- -octalone-2.

In another of its aspects, the present invention is concerned with a method of imparting an odor to materials by applying thereto or incorporating therein an odorimparting amount of l-methyl -octalone-2.

In yet another of its aspects, the present invention is concerned with a process for altering the perfumistic properties of odorant compositions by incorporating lO-methyl- -octalone-2 into an odorant composition.

The fragrance of the octalone of formula I is agreste, balsamic and hay-like. It displays, in particular, honey-like, tonkaand coumarin-like, sweet-irislike, spicy and slightly woody notes reminiscent oflight tobacco.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The octalone of formula I can be used in the manufacture of compositions having a wide variety of perfumistic applications. In particular, it can be used as a component of perfume bases for modern mens lines. Furthermore, the character of compositions having, for example, floral notes, especially those having jasmine, rose or muguet character, can be altered or strengthened with the aid of the octalone of formula I. The same is also true of perfume bases having wood, chypre or fougere character, the perfumistic notes of which are influenced in a desirable manner by the incorporation therein of the octalone of formula I,

Finally, the octalone of formula I also has a fixative action.

The amounts in which the octalone of formula I can be used in odorant compositions can vary within wide limits. In perfume bases, the octalone can be employed. for example in amounts of ca 2-20 wt.% and in finished products such as perfumes, lotions etc. about l-2% can parts by weight:

cinnamon oil Ceylon 5 geranium oil Bourbon 5 musk ambrette 5 vanillin 10% in diethyl phthalate) 5 geraniol pure 20 phenylethyl alcohol 30 nopyl acetate 30 bergamotte oil Reggio 50 lavandin 22/2471 I00 lavender oil 38/407: 300

The addition of 5-10 wt.% of the octalone of formula I to this composition imparts thereto a fuller, warmer note and the lavender character of the composition is decisively intensified.

What is claimed is:

1. An odorant composition which contains an olfactorily-effective amount of IO-methyl- -octalone-2 and at least one carrier commonly used in odorant compositions. 

1. AN ODORANT COMPOSITION WHICH CONTAINS AN OLFACTORILYEFFECTIVE AMOUNT OF 10-METHYL-$1.9-OCTALONE-2 AND AT LEAST ONE CARRIER COMMONLY USED IN ODORANT COMPOSITIONS.
